Terms of use

Last updated: 1 August 2026 · Applies to howust.quest and all modules delivered by J&D B.V.

1. Who we are

This website and the modules described on it are operated by J&D B.V. ("J&D", "we", "us"), a private limited company (besloten vennootschap) registered in the Netherlands.

• Registered address: Zuiddijk 416, 1505 HE Zaandam, Netherlands
• Email: [email protected]
• Telephone: +31 75 303 4120
• Chamber of Commerce (KvK) number: [insert registered KvK number]
• VAT (BTW) number: [insert VAT identification number]

Teaching is delivered online to learners across Canada. We have no office, staff or legal establishment in Canada.

2. Scope of what we provide

We provide educational content: pre-recorded and live instruction, exercise files, reference notes and written feedback on submitted exercises. Nothing more is offered or implied.

In particular, we do not provide:

• career placement, recruitment, job referrals, reference letters or career counselling;
• consulting, data analysis, dashboard building or any other service performed on your or your employer's data;
• accredited, regulated or government-recognised qualifications, licences or professional designations;
• financial, investment, legal, tax, accounting, medical, immigration or any other regulated professional advice.

Datasets, scenarios and examples used in teaching are illustrative. They are chosen to make a technique clear, not to be accurate about any real organisation, market or situation, and must not be relied on for any decision.

3. No guarantees about outcomes

We make no representation, warranty or guarantee regarding employment, promotion, income, business results, admission to any programme, or any other outcome that may follow from taking a module. Any decision you take on the basis of what you learn is your own, and you are responsible for it.

Our certificate of completion records that you took a named module and which exercises you submitted. It is not a diploma, credential, licence or accreditation, is not issued under any Dutch or Canadian educational framework, and confers no professional status.

4. Enrolment and fees

Enrolment is by written agreement following an enquiry. We will confirm the module, the start date, the schedule and the fee in writing before payment is due. A contract is formed when we send that confirmation and you accept it.

Fees are stated in the confirmation, are payable in advance unless we agree otherwise in writing, and are exclusive of any applicable VAT, which is shown separately. Where an employer is invoiced, the employer becomes responsible for payment while the individual learner remains bound by these terms.

Places are limited to 18 per group and are allocated in the order that confirmed enrolments are received.

5. Cancellation and withdrawal

If you are a consumer in the EU

You have a statutory right to withdraw from a distance contract within 14 days without giving a reason. If you ask us to begin delivery during that period and the module starts before it ends, you may owe a proportionate amount for what has been delivered. If you expressly confirm that delivery may start immediately and acknowledge the loss of the withdrawal right on full performance, the right ends once the module is fully delivered.

All learners

• More than 14 days before the start date: full refund, or transfer to a later group at no cost.
• Between 14 days and the start date: transfer to a later group at no cost, or a refund less a 25% administrative charge.
• After the module has started: no refund, because materials and access have been issued. In case of serious illness or comparable circumstances, contact us and we will look for a workable arrangement.

If we cancel or reschedule a module, you may transfer to another date or receive a full refund of fees paid for that module. We are not liable for other costs you may have incurred.

6. Course materials and licence

All teaching materials — exercise files, reference notes, slides, recordings and the structure of the modules themselves — remain the intellectual property of J&D B.V. or its licensors.

On enrolment you receive a personal, non-transferable, non-exclusive licence to use the materials for your own learning and for your own work, including work you do for your employer. You may not redistribute, publish, resell, or use the materials to deliver training to others, and you may not share your access with anyone else.

Work you produce during a module — your own files, charts and dashboards — belongs to you. If we would like to show an anonymised excerpt of your work in a later session, we will ask you first, and you may refuse without any consequence.

7. Live sessions, recordings and conduct

Live sessions are recorded so that learners who cannot attend can follow the module. Recordings capture the instructor's screen and audio. Cameras are optional; if you speak or share your screen, that will be part of the recording, and you may ask us to edit or remove your contribution.

You may not record, screenshot for redistribution, or re-publish any part of a session yourself.

We ask that everyone in a session behaves reasonably towards instructors and other learners. We may remove a participant, without refund, for harassment, discriminatory conduct, sustained disruption, or sharing access credentials.

8. Data you send us

Please do not send us confidential, commercially sensitive or personal data belonging to your employer, clients or anyone else. Exercise submissions should use the supplied files, or your own data with names and identifiers removed. We may delete material that appears to contain confidential information and will tell you if we do.

9. Availability and technical requirements

You are responsible for a suitable computer, a stable internet connection, and access to Microsoft Excel or a Google account. We aim to keep this website and our learning materials available, but we do not guarantee uninterrupted access, and maintenance or third-party outages may cause temporary interruption. Where a live session is lost to a technical failure on our side, we will reschedule it or provide a recorded equivalent.

10. Liability

To the extent permitted by law, our total liability arising out of or in connection with a module is limited to the fee you paid for that module. We are not liable for indirect or consequential loss, including loss of income, loss of opportunity, or loss arising from decisions you make on the basis of material taught.

Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud, or for any liability that cannot lawfully be excluded. If you are a consumer, your mandatory statutory rights are unaffected.

11. Changes

We revise module content regularly; the outline you were sent at enrolment is the version we are committed to delivering, and any material change will be communicated before the start date. We may update these terms; the version in force is the one published here on the date your enrolment is confirmed. Changes to the website itself may be made at any time.

12. Governing law

These terms are governed by the laws of the Netherlands. Disputes will be submitted to the competent court in Amsterdam, the Netherlands. If you are a consumer resident elsewhere, this does not deprive you of the protection of mandatory consumer provisions in your place of residence, and you may be entitled to bring proceedings there.
